Abstract
Torque is transmitted by way of a shaft having an axial groove formed as a keyway therein and a key held in the groove by means of a coin-shaped magnet located in a pocket formed in the floor of the groove. A second element, such as a coupling, is configured to receive the shaft and key therein and has a matching keyway.
